Patent DE-2804432-A1 (DE)
Inventor: MONN WALTER
IPC: F01L7/06
Filed: 1978-02-02
Abstract: A disc-shaped rotary slide valve (14) is arranged in a housing (8, 10). The rotary slide valve (14) has passages (32, 34, 36, 38, 39), which connect the working cylinder chamber (4) of an internal combustion engine to an air intake port (40) and an exhaust port (42) respectively. A cooling line system has coolant chambers (51, 62) in the rotary slide valve (14) and cooling ducts (60) carrying coolant from the radially inner to the radially outer part. Further coolant ducts (64) lead from the outer chambers (62) to a toroidal chamber (66). The coolant feed and discharge ducts (92 and 52) running in the housing (8, 10) lead into and out of the toroidal chambers (51, 66) of the rotary slide valve (14). Annular grooves (53, 94) of the housing (8, 10) lie opposite the toroidal chambers (51, 66) of the rotary slide valve (14). The simple construction permits more intensive cooling. <IMAGE>

Title: Heating system with heat pump - passes mixt. of fresh air and flue gases through heat pump secondary circuit heat exchanger
Inventor: HAAG FRANZ ING GRAD
IPC: F24H4/02
Filed: 1978-03-17
Abstract: The heating system uses a stove or boiler which may be gas or oil heated with a hot water circuit connected to a heat pump. The flue gases (27) are passed through a heat exchanger (12) with a heat exchange coil (9) forming part of the secondary hot water circuit (7, 8) also connected to the heat pump. This heat exchanger (12) can be mounted on an outside wall (20) so that fresh air can be mixed with the flue gases before they are passed through the heat exchange coil (9) and out again to atmosphere. The ratio of flue gas to fresh air is at least 1:2 and preferably 1:10 or more. The mixture is driven through the coil (19) by a fan (18) preceding it, which has its rotor enclosed by a ring (29) which produces a suction effect on the flue gases.

Title: Automatic control of road vehicle - using throttle controlled by determining switching rate based on effective resistance to vehicle motion
Inventor: HEESS GERHARD DR ING
IPC: F16H59/14
Filed: 1978-12-02
Abstract: A road vehicle powered by a turbine is provided with fully automatic power control that reacts to changes in resistance to travel caused by wind resistance, inclination of road surface etc. The motor torque and speed after multiplying by the inertia, are subtracted to provide the pump impeller torque. A divider provides the ratio of motor and pump speeds, the two values address a memory providing the turbine torque. A further analogue computer calculates the dynamic condition of the vehicle to provide an output that is an indication of the change in resistance to the vehicle motor. The throttle control unit receives the value and calculates the necessary switching rate to maintain the specified road speed condition.

Title: Tie up device for round bales - uses foil strip of flexible material instead of conventional thread
Inventor: KRONE BERNARD
IPC: A01F15/14
Filed: 1979-03-23
Abstract: The device is for tying up a round bale of agricultural crop. It has a binding thread, consisting of a binding thread roller, a starter device to initiate the tying up procedure and a blade to cut off the thread at the end of the tie up procedure. The length of the binding thread roller corresponds to the width of the round bale and during the tie-up procedure, the thread so rolls off that it is reciprocated at a regular speed parallel to the axis of rotation of the bale. Instead of the binding thread, a foil strip of flexible material is used. This strip is wound on the foil roller such that on rolling off it covers the bale on its total casing face.

Title: Electrical indicator deriving power from measurement current - using evaluation circuit consuming less than quiescent current
Inventor: FEUCHT WOLFGANG ING GRAD
IPC: G01R15/12
Filed: 1980-07-19
Abstract: An electrical indicator without auxiliary power is esp. for explosive atmospheres and displays a measurement current modified by a measurement parameter and contg. a quiescent current component. It is a highly accurate device which is easily read and insensitive to shocks. The measurement current passes through a measurement resistor and the indicator shows the resistor voltage drop using the energy contained in the current. A voltage regulator in series with the measurement resistor provides a constant voltage independent of the measurement current. The voltage powering an evaluation circuit is derived from the regulator constant voltage. The evaluation circuit contains an analogue-to-digital converter driving an indicator and consumes less current than the quiescent current component. The resistance voltage drop is input to the converter.

Title: Treatment of radioactive residue of waste liquor contg. borate - by adjusting sodium boron molar ratio during concn. by evapn.
Inventor: BEGE DIETMAR
IPC: G21F9/22
Filed: 1980-07-31
Abstract: Treatment of radioactive residues of waste liquors contg. borate, which are conc. by evapn., involves treating the concentrates with NaOH soln. in a first vessel to a Na/B molar ratio of ca. 0.7 to 0.3. The concentrates are then transferred to a second heatable vessel in amts. determined by integrated measurement and conc. to at least double the solids content. The conc. concentrates are then transferred to a transport vessel and placed in a safe store. Flow through the first vessel is assisted by an outer pipework cycle contg. a heat exchanger and a pump and supplied with NaOH soln. The adjusted concentrate is transferred to the heatable vessel from this cycle and conc. to a solids content of min. 50 (60) wt.%. The amt. of waste is reduced and the space required for intermediate storage is kept small without impairing later processing to a state suitable for final storage.
